Understanding the Power Reliability Challenge in FTTH Networks
Fiber-to-the-home (FTTH) subscriber installations depend on a chain of always-on customer-premises equipment: routers, modems, ONTs, ONUs, gateways, and CPE devices that must stay connected to maintain service continuity. A common industry pain point is that these devices often reboot or lose service during short power outages, voltage drops, or unstable grid conditions. When a subscriber's connection drops even briefly, it can disrupt broadband service, security monitoring, or remote work continuity. For telecom operators, Internet Service Providers (ISPs), broadband network companies, fiber network operators, and system integrators, this reliability gap is not a minor inconvenience—it is a recurring operational and customer-experience issue that must be addressed at the hardware level.
Why Mini UPS Solutions Matter for Low-Power CPE
A Mini UPS—a compact, DC-based uninterruptible power supply designed specifically for low-power network equipment—offers a targeted way to bridge these short interruptions without the complexity of traditional AC UPS systems. Unlike general-purpose backup power products, a Mini UPS built for FTTH subscriber installations is engineered around the actual electrical profile of CPE devices: their voltage requirements, working current, and peak or startup current behavior.
Matching Voltage, Current, and Peak Load Requirements
One of the most overlooked risks in DC backup deployment is improper UPS selection regarding voltage, current, peak load, or connectors, which can lead to application failure. A router or ONT may operate normally under steady load but draw a higher peak current at startup, and if the backup unit cannot supply that peak, the device may fail to boot correctly even when battery power is available. This is why evaluation based on real device voltage, working current, peak/startup behavior, and installation environment—rather than generic specifications—is essential to a successful deployment.
Shanghai Mylion New Energy's Approach to DC Backup Power
Shanghai Mylion New Energy Co., Ltd., operating under the brand MYLION and headquartered in Shanghai, China, positions itself as a global B2B provider of Mini UPS products, DC backup power solutions, and project support for telecom, ISP, broadband, and security applications. The company functions as a B2B backup power partner and OEM/ODM project partner, drawing on 13+ years of experience in lithium battery technology and 10+ years of experience in Mini UPS development.
Rather than offering a one-size-fits-all product, MYLION's differentiated advantage lies in technical confirmation and connector/cable matching to reduce selection errors, supported by evaluation of solutions based on real device voltage, working current, peak/startup behavior, and installation environment. This approach is intended to support more reliable DC backup deployment and reduce avoidable selection risks for professional project customers—directly addressing the voltage, current, and connector mismatches that commonly undermine Mini UPS installations in FTTH environments.
Product Portfolio Aligned with FTTH Subscriber Needs
MYLION's product matrix reflects the varied electrical demands found across subscriber-side equipment:
- The 12V Standard Series, including the MU26W (2.5A continuous / 3A maximum output, 18.72Wh battery capacity, DC5521 input / DC5525 output), MU48W (29.6Wh energy, center-positive DC5525 output), and MU68W (44.4Wh energy, maximum 36W output), targets entry-level to mainstream broadband backup for routers and ONTs.
- The 12V Long-Runtime Series (MU635W / MU635L) provides 75.6Wh of battery energy at the same 2.5A continuous / 3A maximum output, addressing longer residential or remote-area outages.
- The 12V High-Power Series (MU65W) supports 4A continuous / 5A maximum output (60W total) with 56.16Wh energy, suited to high-performance WiFi equipment and storage-integrated gateways that exceed standard 2.5A thresholds.
- The 12V High-Power Long-Runtime Series (MU35W / MU35L) combines 4A continuous / 5A maximum output with 75.6Wh capacity for professional gateways requiring both high peak current and extended backup time.
- The 12V + USB Multi-Output Series (MUJ46 and MUJ435) delivers simultaneous 12V DC and 5V USB-A/USB-C outputs within an 18W system limit, suited to small office/home office setups that need to power a router and a USB accessory together.
- The AC-Input Dual Output Series (ML1202AC) uses LiFePO4 chemistry with a 100–240V AC input and two 12V DC ports (2A each, 24W total), simplifying deployments such as combined ONT and router installations without an external DC adapter.
- Two directions—the MUC85 (USB-C PD Mini UPS, 65W standard/100W max input) and the MU248 (24V/48V telecom backup direction)—are under project-evaluation development for higher-power WiFi 6/7 devices and higher-voltage wireless CPE or radio bridge equipment.
Technical Capabilities Supporting Reliable Deployment
MYLION's technical portfolio covers 12V DC systems up to 60W, LiFePO4 chemistry integration, and emerging USB-C PD 100W input/65W output capabilities. Compatibility extends to routers, ONTs, ONUs, modems, gateways, CPE devices, and security/CCTV equipment, subject to electrical verification—an important qualifier, since compatibility in Mini UPS deployment always depends on confirming actual device specifications rather than assumptions. On the compliance side, MYLION maintains industry certifications including UN38.3 and MSDS on a model-specific basis, along with adherence to lithium battery transport documentation and model-specific compliance requirements, both relevant considerations for lithium-based backup power shipped internationally.
Service Model for B2B and OEM/ODM Partners
For telecom operators, ISPs, system integrators, distributors, brand owners, and OEM/ODM customers, MYLION offers B2B project support, OEM/ODM services, and sample validation. The service scope includes requirement analysis, model matching, sample testing support, connector/cable matching, private labeling, and documentation coordination, with delivery capability extending to managed pilot evaluation and mass-production preparation. Pricing follows a custom enterprise and project-based quote structure, reflecting the technical variability across different FTTH deployment scenarios. After deployment, after-sales support continues through technical evaluation, model matching, and project-specific documentation coordination, reinforcing the company's role as a project partner rather than a one-time hardware vendor.
Looking Ahead
As FTTH networks continue to expand and subscriber-side equipment becomes more power-diverse—from standard routers to WiFi 6/7 gateways and higher-voltage wireless CPE—the need for precisely matched DC backup power grows accordingly. MYLION's model of evaluating real device electrical profiles before recommending a Mini UPS, combined with a structured product range spanning standard, long-runtime, high-power, multi-output, AC-input, and emerging USB-C PD and 24V/48V directions, reflects a methodical response to this challenge. For telecom operators, ISPs, broadband network companies, and system integrators evaluating Mini UPS options for FTTH subscriber installations, understanding these voltage, current, and connector-matching principles—an area MYLION emphasizes throughout its project support process—is a practical starting point for reducing avoidable deployment failures.
